摘要： A method, and apparatus for accomplishing the method, for determining the frequency of an RF signal that operates by sequentially applying a received RF signal to sequentially selected individual filters having predetermined frequency pass bands and comparing the magnitudes of the filtered and unfiltered RF signals. The frequency of the RF signal is determined as being within the predetermined frequency pass band of a filter that outputs a largest magnitude output signal relative to the magnitude of the RF signal. Signals of insufficient magnitude are not processed by the system.

摘要： A three input comparator facilitates the comparison of a signal to the greater of two different reference voltages in a manner which mitigates propagation delay. A first differential pair of transistors facilitates comparison of the two reference voltages to one another, while second and third differential pairs of transistors facilitate comparison of the signal to the higher of the two reference voltages.
摘要翻译：三输入比较器有助于以减轻传播延迟的方式将信号与两个不同参考电压中的较大者进行比较。第一差分对晶体管有助于将两个参考电压彼此进行比较，而第二和第三差分对晶体管便于将信号与两个参考电压中的较高者进行比较。

摘要： A vehicle having a plurality of antennas each in association with a communications transmitter device disposed within the vehicle to thereby provide multiple signal transmission sites. At least one antenna is disposed substantially at a top site of the vehicle and at least one antenna is disposed substantially at a bottom site of the vehicle, thus providing antenna coverage irrespective of the spatial orientation of the vehicle. The invention includes a communications system employing a multiplicity of antenna sites as well as methodology for providing a communication link from a vehicle to a receiving site by incorporating the communications system. In this manner, vehicle occupants are provided with a communications link from the vehicle, irrespective of the position of the vehicle. Thus, if one antenna is shielded from transmission because it is situated at a top site of a vehicle and the vehicle is upside down because of a mishap, another antenna which is situated to be operable from a non-shielded site (e.g. a bottom site of the vehicle) will provide effective signal transmission. The invention thereby provides enhanced safety and security for vehicle occupants in most travel environments.
摘要翻译：一种具有多个天线的车辆，每个天线与设置在车辆内的通信发射机设备相关联，从而提供多个信号传输站点。至少一个天线基本上设置在车辆的顶部位置处，并且至少一个天线基本上设置在车辆的底部位置处，从而提供与车辆的空间取向无关的天线覆盖。本发明包括采用多个天线位置的通信系统以及通过并入通信系统来提供从车辆到接收站点的通信链路的方法。以这种方式，不管车辆的位置如何，车辆乘客都具有来自车辆的通信链路。因此，如果一个天线由于位于车辆的顶部位置并且车辆由于事故而被倒置而被屏蔽而不被传输，则另一个天线位于可从非屏蔽位置（例如，底部位置的车辆）将提供有效的信号传输。因此，本发明为大多数旅行环境中的车辆乘客提供了增强的安全性和安全性。
